Now, when you use Norton Ghost to backup your active partition, what you sometimes ... ok most of the time might get is a PQI error. This is in my opinion because you're in the OS while backing it up ... it's really well documented on a Radified forum. PQI Error

My solution to the problem was to run scandisk from my Xp Installable PE (Preinstalled Environment). That fixed the PQI error, but I still have to really test the integrity of the hwole process by actually completing a restore.
